摘要：
A semiconductor integrated circuit is provided that can prevent an internal voltage from the voltage generating circuit from varying during a long term. The semiconductor integrated circuit of the present invention includes a voltage generating circuit configured to generate a reference voltage; a function circuit configured to operate by using the reference voltage; a first capacitance connected to a first node between the voltage generating circuit and the function circuit; and a switch provided between the voltage generating circuit and the first node. The switch is in a turned-off state at least for a period during which the function circuit is in an activated state.
